Newbie Schema Usage

I'm all brand new to this OpenLDAP stuff, and am trying to add a schema. (I
take it this is what I need to do in order to allow the objectClass of
'inetOrgPerson', thus allowing me to use the 'mail' attribute for a person
record?!)

Here's the top bit of my slapd.conf:

include /usr/local/OpenLDAP/etc/openldap/schema/core.schema
include /usr/local/OpenLDAP/etc/openldap/schema/inetorgperson.schema

# Define global ACLs to disable default read access.

# Do not enable referrals until AFTER you have a working directory
# service AND an understanding of referrals.
#referral ldap://root.openldap.org
